Our Sellers drill grinder is used primarily for sharpening larger diameter High Speed Steel (HSS) drills, typically over 1.00″ in diameter. This grinder utilizes a camming action of the drill against a stationary grinding wheel to sharpen the end of the drill to a rolled drill point at the desired drill point angle. The drill point angle may be adjusted per customer requirement depending on what material they are machining, or to achieve a desired point angle at the bottom of a hole.
